Study on Fractal of Gas Distribution in Coal and Gas Outburst Prediction

摘要

Coal and gas outburst is serious threat of safety production in coal mine.It is a very complex dynamic phenomena.In view of the coal and gas outburst occurred emission forecast, this article can the mine gas drainage design provides the basis.In the forecast, it put forward on the basis of gas distribution of multiple points d thought and given its corresponding mathematical model.In this paper researched the coal and gas outburst in relative scale of don't variable fractal dimension.It gives the fractal dimension of calculation formula.It provides a criterion for coal and gas outburst prediction.
